​I've been TTC for over a year now. My last cycle was only 20 days (usually around the 30 day mark) with 3 days of medium dark brown and towards the end pink spotting, light cramps, slight nausea only as soon as I woke up, fatigue and pain in my sciatic nerve. This happend about two weeks before my scheduled period. My scheduled period has still not come and with a negitive test I'm unsure if this was a very early short period or signs of early pregnancy? Please help as I cannot get into the doctors for another week and would like some help if anyone has had anything similar. Thanks :)
